SparkFun Nano Power Timer - TPL5110

The SparkFun Nano Power Timer - TPL5110 is a power-efficient device designed to conserve energy in your projects. Consuming a mere 35nA of power, it ensures that your project is only active when necessary. It's perfect for applications where intermittent operation is required, such as sensor polling, data posting, logging activities, or any other tasks that don't require continuous power. With this timer, there's no need to keep your microcontroller running all day just to perform hourly tasks.

The timer's delay can be configured using resistors. The SparkFun Nano Power Timer comes with a six-way DIP switch linked to five preinstalled resistors, allowing you to select the appropriate delay for your project. The sixth switch is connected to a pad for adding your own PTH or SMD resistor. The corresponding delay for each resistor combination is printed on the board for easy reference. More than one switch can be selected to combine resistors in parallel, providing up to 26 options excluding the custom resistor.

Capable of handling voltages between 1.8V and 5.5V, and current up to 1.1A, the Nano Power Timer offers time intervals ranging from 100ms to two hours. This flexibility makes it suitable for a wide range of applications. Additionally, the timer comes with a button for quick override, allowing you to activate your project whenever necessary.

Key Features:

• Supply Voltage: 1.8V to 5.5V
• Current consumption at 2.5V: 35nA Typical (50nA Max)
• Selectable Time intervals: 100ms to 7200s (2 hours)
• Timer Accuracy: 1%
